Installed a teague universal mount oil filter bracket with HP6 filter on my stock 502 magnum. It was an easy install on the transom and oil temps seem to have decreased about 15 deg at extended periods at WOT. It is also nice to know that there is a little bit extra oil in the system just in case. Just make sure that you save your old temp sender or buy new sender and matching gauge. I ordered just a new sender and the readings on my original gauge were off. Installed old sender and readings were back to the normal ranges. Also, there are 2 small holes for senders, make sure that you plug the one that you don't use.
